What is a third-level domain name?
The portion of the domain name that appears before the second-level domain name, separated by a dot, is the third-level domain name. The most common third-level domain name is www. Third-level domain names, also called subdomains, are often used to categorize special sections of a Web site, such as press releases at “press.verisign.com” or investor information at “investor.verisign.com”. A third-level domain name does not have to be registered and is created on the Web site host server. However, the .name registry does allow registration of third-level domain names so that individuals may register domain names that match their actual names such as firstname.lastname.name.
